Application iledictobel' 6i, 1813. Serial No. 793,303.

To all whom it may concern.' Be it known that l, CARL Gr. UnLIN, a citizen `of the United States, Aresiding at Seattle, in the county of King and State of lil'ashington, have invented certain'new and useful improvements in Submarine Vessels,

of which the following is a speclficatlon.

This invention relates to submarine vestels; and its object is `the provision of improved means for controlling the longitudinal inclination of the vesl when the same :is traveling through the Water for the purpose of steering the vessel in downward and upward directions to carry the vessel to'selected depths.

A. further object of the invention 1s to provide means for automatically regulating the lateral rolling of the vessel and tending to maintain the same in upright position.

lVith these ends in View, the nventlon consists in the novel construction and adaptation of devices,- as Will be hereinafter described and'claimed.

In the accompanyingdrawings, Figure 1 is a side elevation of a submarine boat with the present invention applied thereto. Fig. 2 is a transverse view taken substantially through 2-2 of Fig. 1. Fig. 3 is a like view through 3-3 of Fig. 1. F ig. 4 is a perspective view of the devices employed for counteracting rolling movements of the vessel. Fig. 5 is a perspective view of a pair of boat-guiding ns and the coupling connecti ons therefor.

The reference numeral 10 designates the hull of a submarine vessel provided with a Water ballast tank 11 and having a steering rudder 12 and a. power driven propeller 13,

as usual.

Adjacent to the .front end of the vessel and upon opposite sides of the same are blades or Iins 14 which are, intermediate their lengths, rigidly secured. to or formed on the outer ends of shafts 15. These shafts are arranged in axial alinement and are journaled in bearing boxes 16 and stuffing boxes 17 where they .extend through .the

shell of Athe hull. The inner ends of the shafts 15 are provided with crank-arms 18 which are connected by a crank-pin 19. A reachsrod 20connects said crank pin with an operatingflever.21` Similarly, near the stern is provided at opposite sides of the vesseha pair of blades or fins such as 141 carried by the protruding ends of alined shafts 1,51 having crank arms 181 which are operatively connected by a reach-rod 201 with an operating lever 211;

22 is a linlr'connected from one end by a pivotal pin 23 to the reach rod 20 and hav inga hook-24 at its free end 'for engagement with a stud 25 provided on the other rod 201.

The operation of the invention Iso far described is as followsf Vhen the aforesaid fins are rotated about their axes through the 'instrumentality of the levers 21 or 211 to in oline the fins with their forward ends lowermost, the currents of water eausedby the progress of the vessel-.will act upon the fins to depress the same.l If the fins are inclined to have the rear ends thereoflowermost, then, on the contrary, thetendenoy of the water currentsisto exert an uplift on the fins.v The fins, when operated in unison by utilizing the 'link 22, as before stated, to couple the reach rods of both the forward and rear pair of fins, will serve to cause the boat to ascend or descend, as the case may be, in the water without disturbing the lon-v gitudinal trim or inclination of the vessel. Under such conditions, however, the vertical movements of the vessel would be accomplished with less speed than Where the forward and rearward fins are jreversely disposed. For example, when the forward fins aredirected to swerve the boat at that end downward and t'hose at the rear end upwardly, the longitudinal axis of the vessel 1s quickly brought into the line in which the vessel is to be driven, fins into ajplane parallel with the vessels axis, the vessel is propelled with less resistance 'loybthe Water than Whentaking an oblique forward course.l y

I also provide in proximity to the midlength ofthe vessel a pair of lins 26 and 261 which are respectively carried on shafts 27 and 271 disposed in axial alinement and extending transversely through stuffing-boxes 28 and journaled in the latter and bearingboxes 29. Provided on the inner ends of these shafts' are forwardly extending crankarms 30 and 301. These crank-arms are each provided with a slot 31 to receive the branch arms 32 of the stem 33 of a T-shaped lever. Said lever is fulcrumed upon a pin Y9o and upon restoring the 34: which is arranged longitudinally of the 36 depending upon the lever stem 33 is affected by gravity to retain the same in a' vertical position.

Should the vessel from any cause get out of equilibrium, and roll or ti t transversely, the weight 36 will assert its power to retain the l'lever so that the arms 32 thereof will be horizontal, but inasmuch as the shafts 27 and 271 are tilted with the boat, the arms 32 will be influenced to rotate the fins 26 and 261 in reverseI angular directions and with the forward edge of the downwardly tilted fin inclined upwardly/,and the other fin Vinclined downwardly. In such relative positions, the advance movement of the vessel will cause the water to impinge the respective fins so that they will coperate for returning the boat to normal position by pushing up on the lower one and down upon the upper one. When the vessel is restored to upright position, the pendulum-like lever will be held by said weight so that the arms 32 thereof will yieldingly hold the ns 26 and 261 in a plane with each other and parallel with the longitudinal axis of the Vessel. v

vessel in proximity to the bow and stern thereof, a blade provided on the outer end of each -of said shafts, crankarms provided on the inner ends of said shafts, crank-pins respectively coupling the crankarms of the bow and stern shafts with each other, reach rods connected with said crankpns for operating the respective shafts to regulate the nclinatioris'of the blades thereof, and leversreonnected to said rods whereby the blades may be coincidentally adjusted.

2. The combination withasubmarine vessel of pairs of axially alined shafts extending through the shell of the vessel in proximity respectively t the bow and stern thereof, a blade on the outer end ofl euch f said shafts, crank arms on the inner ends of the shafts, pinsconnecting said crank arms, means for coincidentally adjusting-isaid blades, a pair of axially alined yshafts in proximity to the midlength oi the vessel, slotted crank arms on the inner ends of said last-named shafts; a T-shaped lever the branch-arms of which are supported .by said:y
